无法在文件中查找字符串并使用 Inno Setup 填充它？

I have demo.properties文件，我可以加载文件并迭代以获取其中存在的所有值。

hibernate.connection.username=jack
hibernate.connection.password=queen
hibernate.connection.url=jdbc:jtds:sqlserver://localhost/cabinet

但是当我得到第 1 行（能够逐行获取但无法获取特定字符串）并且我想填充 jack 并存储到用户名字符串中，类似地将皇后存储到密码字符串中，将本地主机存储到数据库字符串中。这是我要获取的代码/逻辑价值观。

procedure InitializeWizard;
var  

  xmlInhalt: TArrayOfString;  
  k : Integer;
  CurrentLine : String;
  Uname : String;  
   Password : String;
   HostName : String;
   STR : String;                        

begin
          LoadStringsFromFile('C:\demo.properties', xmlInhalt);
          for k:=0 to GetArrayLength(xmlInhalt)<>-1 do
          begin
            CurrentLine := xmlInhalt[k];
            MsgBox(CurrentLine, mbError, MB_OK);
            if (Pos('hibernate.connection.username=', CurrentLine) <>-1 ) then
                begin
                              MsgBox(CurrentLine, mbError, MB_OK);
                    Uname := Pos('://', CurrentLine);
                    STR :=IntToStr(Uname);    
                    STR :=IntToStr(Length('://')); 
                    Password := Pos(':1', CurrentLine);
                    HostName :=Password -Uname;                  

              end;    
         end; 
end;

请帮助我满足我的要求。我们将不胜感激您的帮助。

If the TStrings班级已发表NameValueSeparator and Values属性，我建议使用它。但它没有，所以这里有一个解决方法的代码（它使用TArrayOfString，但是很容易将其修改为TStrings class):

[Setup]
AppName=My Program
AppVersion=1.5
DefaultDirName={pf}\My Program

[Code]
function TryGetValue(const Strings: TArrayOfString; const Name: string;
  out Value: string): Boolean;
var
  S: string;
  P: Integer;
  I: Integer;
begin
  Result := False;
  { loop through the array }
  for I := 0 to GetArrayLength(Strings) - 1 do
  begin
    { store the currently iterated string into a local variable }
    S := Strings[I];
    { try to get position of the name value separator ('='in this case) }
    P := Pos('=', S);
    { if the separator was found on this line, and a text on the left of }
    { it matches (case insensitively) the input Name parameter value, we }
    { found what we were looking for, so return True and the rest of the }
    { text after the found separator }
    if (P <> 0) and (CompareText(Copy(S, 1, P - 1), Name) = 0) then
    begin
      Value := Copy(S, P + 1, MaxInt);
      Result := True;
      Exit;
    end;
  end;
end;

{ do note, that this function may not conform the RFC 3986 specification; }
{ preferred way should be e.g. InternetCrackUrl, but with this particular }
{ scheme (jdbc:jtds:sqlserver) it didn't crack the URL properly }
function GetHostName(const URL: string): string;
var
  P: Integer;
begin
  Result := '';
  P := Pos('://', URL);
  if P <> 0 then
  begin
    Result := Copy(URL, P + 3, MaxInt);
    P := Pos('/', Result);
    if P = 0 then
      P := MaxInt;
    Result := Copy(Result, 1, P - 1);
  end;
end;

procedure InitializeWizard;
var  
  URL: string;
  HostName: string;
  UserName: string;
  Password: string;
  StrArray: TArrayOfString;
begin
  if LoadStringsFromFile('C:\File.txt', StrArray) then
  begin
    TryGetValue(StrArray, 'hibernate.connection.url', URL);
    HostName := GetHostName(URL);
    TryGetValue(StrArray, 'hibernate.connection.username', UserName);
    TryGetValue(StrArray, 'hibernate.connection.password', Password);
    MsgBox(Format(
      'HostName: %s' + #13#10 + 'UserName: %s' + #13#10 + 'Password: %s', [
      HostName, UserName, Password]
    ), mbInformation, MB_OK);
  end; 
end;
